HYDROOARBON-BURNER.

Specification of Letters Patent.

Application filed September 6, 1912. Serial No. 718,938.

T 0 all whom it may concern.

Be it known that I, WALTER E. HUENE- rnnn, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Hydrocarbon-Burners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in hydrocarbon burners of the type employed with oil stoves,--the object of the inven tion being to provide simple and efficient means for raising, lowering and guiding the combustion chamber member; for locking said member in its lower operative position, and for supporting said combustion chain ber member in elevated position above the wick.

lVith this object in view, the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims.

In the accompanying drawings, Figure l is a sectional View of a burner embodying my improvements and showing the parts in their normal operative position. Fig. 2 is a similar view showing the combustion chamber member elevated, and Figs. 3 and 4 are detail views.

1 represents the wick tube member, comprising concentric tubes 28, spaced apart to form between them a wick chamber closed at its lower end. A wick 4 is located in this chamber and provided with a perforated metal holder 5 to be engaged by wick raising and lowering means 6. The wick tubes are provided at their upper ends with seats 78 to receive the lower ends of concentric foraminat-ed shells 9-10 of the combustion chamber member 11,-the combustion chamber being formed by and between said shells. The inner shell of the combustion chamber member is provided at its upper end with a perforated cap 12 and at its lower end with a perforated cap 18. The lower cap 13 may be disposed more or less distance above the lower end of the inner shell 9 and from this lower cap a plurality of arms 14 depend,said arms being rigidly secured to the cap and disposed to form a spider 15 a ng a h llow ce te A guide rod 16 enters the hollow center of the spider 15 and may be rigidly secured to the latter in any suitable manner. This rod extends downwardly into the cylindrical chamber formed by the inner wick tube and passes freely through the hollow center of a spider 17 secured within said cylindrical chamber, any suitable means being provided to fasten said spider to the wall of the inner wick tube. By means of this construction, the combustion chamber member will be guided in its "ertical movements and the proper cooperative relation between the raising and lowering devices (hereinafter explained) will be insured.

If desired the rod 16 may be secured to the spider 17 Within the wick tube member and permitted to pass freely through the spider 15 in the combustion chamber member. The spider 17 may be provided with a plurality of lugs 18 for the attachment of a ring 19 having a plurality of arms 20. Each of the arms 20 is made with an inclined edge 21 and with a seat 22 at the upper end of said inclined edge,a stop shoulder 23 being provided at one end of said seat to limit the rotary movement in one direction of the combustion chamber member when the latter is in its elevated position.

It is apparent that when the combustion chamber member is in its lower operative position and it is desired to raise the same, the turning of said combustion chamber member will cause the lower ends of the arms of the spider 15 to rise upwardly on the inclined edges of the arms 20, thus raising the combustion chamber member until the lower ends of the arms of spider 15 rest upon the seats 22 at the upper end of the arms 20, when the combustion chamber mem ber will be supported in its elevated position. When the combustion chamber member is turned in its reverse direction, the arms of the spider 15 will move off of the seats 22 and the weight of the parts will cause the arms of said spider 15 to ride downwardly on the inclined edges 21 of the arms 20 and the combustion chamber member will become seated on the upper ends of the tubes of the wick tube member.

One of the arms of the spider 15 is provided with a slot or openin 24: and one of the arms 20 is provided with a laterally projecting lug or extension 25, W en the corn- 1 Patented Aug. 19,1913.

bustion chamber member shall have been lowered to its normal operative position with relation to the wick, as above explained, a partial rotation of said combustion chamber member will cause the laterally projecting lug or extension 25 on one of the fixed arms 20 to pass through the slot or opening Qei in one of the arms of the spider 15 carried by the combustion chamber member, and thus the latter will be locked in its lower operative position.

Slight changes might be made in the details of construction and' arrangement of the-parts without departing from the spirit of my invention or limiting its scope and hence I do not wish to restrict myself to the precise details herein shown and described.

Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is:

1. In a hydrocarbon burner, the combination with a wick tube member and a combustion chamber member, of a guide rod entering said members and fixed relatively to one of them, spiders secured to the respective members, one of said spiders having inclined edges and also provided with seats to coact with the other spider to raise the combustion chamber and then sustain it in elevated position.

2. In a hydrocarbon burner, the combination with a wick tube member and a combustion chamber member, of a spider secured to one of said members and provided in one of its arms with a slot or opening, a plurality of arms secured to the other member and having inclined edges to cooperate with said spider for raising and lowering the combustion chamber member and one of said arms having a lateral projection to pass through the slot or opening in the arm of the spider for locking the combustion chamber member in its-lower operative position.

3. In a hydrocarbon burner, the combination wit-h a wick tube member and a combustion chamber member, of an upper spider secured to the combustion chamber member,a lower spider secured within the wick tube member and a plurality ofarms projecting upwardly from said lower spider and having inclined edges to coope ate with the upper spider for raising the combustion chamber member, one of said arms having a lateral projection and the upper spider having a slot or opening to receive said lateral projection for locking the combustion chamber member in its lower operative position.

4:. In a hydrocarbon burner, the combination with a wick tube member and a combustion chamber member, of spiders secured to said members, a rod passing through said spiders and secured to one of them, and a plurality of arms projecting from one of said spiders and having inclined edges to cooperate with the arms of the other spider for efiecting the raising and lowering of the combustion chamber member relatively to the wick tube member.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
